is it just a matter of time that the president could get covid? >> i wouldn't say it's just a matter of time. but of course, it is possible that the president, like any other american, could get covid. the bottom line is he is vaccinated and boosted. he is very well protected. he's got very good protocols around him to protect him from getting infected, but there's no 100% anything. >> reporter: this as a new report today from the cdc finds most americans have been infected by the virus at least once, fueled most recently by that omicron surge. by february, about 58% of all americans and 75% of children under 17 had detectable antibodies. but doctors warn that protection may not last. >> how long does that protection last? and that question hasn't been answered in terms of prior infections. but we do have that information from vaccines that show that they continue to be protective and effective in preventing hospitalization and death. >> reporter: with infections climbing across 35 states and territories, the white house now

trying to expand access to the anti-viral drug paxlovid at 40,000 pharmacies and clinics. and test to treat sites where people at high risk of complications can get tested and treated with paxlovid during the same visit. >> what i am recommending to family and friends is, if you get covid, you should see a provider and make that assessment with your provider. a lot more people are eligible and would benefit than i think people think. >> and cecilia vega live with us from the white house. of course, we wish the vice president a quick recovery here. cecilia, i know you're tracking another developing headline tonight. pfizer now asking for authorization of the first booster shot for children 5 to 11 and, of course, you reported there the vice president already had her second booster shot, available, of course, to american adults over 50. where do we stand big picture on that? how many adults over 50 have gotten that second booster shot and any news when the rest of adults might have access to those boosters, given the rising case numbers across the country? >> reporter: yeah, david, here's what we know right now. we're tracking about more than 4 million people over the age of 50 who have gotten that second

shot. there could be another round of boosters come this fall, but we don't know which age group yet that will target. but here's this. officials are hoping that basically this second round of boosters, other round of boosters, could be a new and improved type of shot, one that would last longer and could work against future variants. david, as for the vice president, we're told that president biden called her today to check in and again, at this hour, she is asymptomatic. >> cecilia vega leading us off here tonight. cecilia, thanks, as always. we're going to turn now to the war in ukraine. tonight, the u.s. reacting after russia's foreign minister 24 hours ago warned of the dangers of a nuclear conflict. tonight, u.s. defense secretary lloyd austin with strong words in response, as he rallied allies in a meeting in germany. more than 40 countries planning new aid to ukraine, including germany, now sending heavy weapons for the first time. secretary austin today warning that in nuclear conflict, all sides lose. and tonight, our team witnessing the telling image in kyiv, statues originally put up to

honor ukraine's friendship with russia now coming down. marcus moore in kyiv tonight. >> reporter: tonight, the u.s. responding to russia's warning that tensions with the west over ukraine could risk world war iii and nuclear conflict. >> that kind of rhetoric is very dangerous and unhelpful. nobody wants to see a nuclear war happen. it's a war that, you know, where all sides lose. >> reporter: u.s. defense secretary austin was in germany meeting with military officials from more than 40 countries and vowed to move, quote, heaven and earth, to help arm ukraine. he thanked germany for changing long-standing policy and for the first time agreeing to send 50 anti-aircraft tanks to ukraine. and he expanded on the u.s. wanting to see russia weakened. >> we would like to make sure, again, that they don't have the same type of capability to bully their neighbors. >> reporter: in moscow today, u.n. secretary-general antonio guterres met with vladimir putin and said an

agreement in principle had been reached for the u.n. and international red cross to help evacuate civilians trapped inside the azovstal steel plant in mariupol. previous agreements to establish safe corridors for the thousand civilians there have failed repeatedly. and concern now turning to transnistria, a russian-backed breakaway region in moldova along ukraine's southwestern border. explosions there reportedly destroying two soviet-era radio towers, according to local authorities. but ukrainian intelligence officials say they fear false flag attacks could be used as an excuse to send the hundreds of russian troops stationed there into western ukraine. today in the capital, a shift in the cultural landscape. crews here in kyiv have been working for hours to remove this massive bronze statue. it's stood here since 1982 and was meant to represent friendship between russia and ukraine. they're taking it down now in response to the war. crowds gathered as the statue was dismantled amid cheering.

>> and marcus moore back with us again tonight from the ukrainia capital. and marcus, russia now suspending natural gas deliveries in parts of europe for the first time, specifically to poland and bulgaria. and of course, we took special interest in poland, given the amount of reporting, you've been there, i've been there with the team, reporting on the number of refugees accepted in poland during this russian war, this invasion on ukraine. >> reporter: david, it's also been a logistical hub for weapons and other aid to go to ukraine, and so, russia cutting off natural gas supplies to poland could be seen as punishment. it is also worth noting that russia has been trying to prop up its currency amid deep sanctions and said that it would only accept rubles for payments of its natural gas. both poland and bulgaria say they have sufficient reserves and also alternative sources for energy. david? >> marcus moore live in kyiv for

us again tonight. thank you, marcus. back here at home tonight and to that developing headline as we came on the air tonight, the audio tonight of house republican leader kevin mccarthy and his concerns about members of his own party, after what the country, what the world witnessed on january 6th. leader mccarthy asking at one point about some of his own republican colleagues, asking, "can't they take away their twitter accounts," and saying the country was "too crazy." here's our chief washington correspondent jonathan karl with the audio tonight. >> reporter: you can hear the anguish in kevin mccarthy's voice. four days after the january 6th attack on the capitol, he is worried that there will be more violence. >> tension is too high, the country is too crazy. i do not want to look back and think we caused something or we missed something and someone got hurt. >> reporter: the audio tapes obtained by "new york times" reporters jonathan martin and alex burns for their upcoming book "this will not pass" show that mccarthy was worried that some of his own colleagues, republican members of congress, are fueling the violence. >> this is serious stuff people

are doing that has to stop. >> reporter: he mentions republican congressman matt gaetz, saying he is going to call him to tell him to knock off his incendiary rhetoric. >> i'm calling gaetz, i'm explaining to him, this is serious [ bleep ] and cu this out. >> reporter: he is so concerned, he asks why twitter, which had recently banned donald trump, cannot ban some of his fellow republican members who he believes are inciting violence. >> can't they take their twitter accounts away, too? >> reporter: the audio shows that mccarthy was genuinely and rightly concerned about more violence breaking out in america. but his suggestion that twitter should ban the accounts of some of his fellow republicans more than anything that has come out so far will be used by mccarthy's enemies and complicate his efforts to become the next speaker of the house. david? >> jon karl with the audio tonight. jon, thank you. we are following fast-moving developments involving the kidnapping of a 3-month-old baby boy from his grandmother's home as she was bringing the groceries in. tonight, that baby has been found in san jose after a desperate 20 hours. the fbi joining the manhunt, and tonight, several potential

the trump era policy, which permits the expulsion of migrants without allowing them to seek asylum due to the pandemic, was set to expire on may 23rd. >> it is not an immigration tool. it is a health authority and one the cdc, our health experts of course, do have authority to make a decision about. and they've made the decision that the conditions no longer exist to keep title 42 in place. >> reporter: state attorneys general involved in the pending lawsuit celebrating. >> it's a big win, i think, for law.er security and the rule of- >> reporter: eddie sanchez owns a gym in eagle pass just feet from the border. when you hear that title 42 might get rolled back, does it matter to you, living here, seeing this every day? >> my only concern is that they're able to stop what's going on. if we can go back to how it was when there was very minimal coming through, that's what i want to go back to. >> reporter: last month, a record number of encounters at the southern border. over 220,000. 28% making at least one other previous attempt in the last year.

our cameras capturing several groups of migrants apprehended within hours on a recent embed with agents. what does title 42 do for you guys? >> it certainly is a tool that the cdc offered up as an expulsion authority. but we know it's not going to last forever. >> reporter: and tonight, migrants like julio, who was expelled once before, say they look forward to the policy's end and the chance to remain in the united states. saying, "it gives us the opportunity to process our political asylum." >> and mireya villarreal joins us now from the texas/mexico border. and mireya, bottom line here, how does this pending order halting any early lifting of title 42 actually impact that set date of lifting it on may 23rd? >> reporter: well, you know, david, the clock is ticking on that temporary restraining order. there will be a larger hearing on may 13th, but as of right now, it's still very unclear if
